To all whom it may concern:

Be it known that I, GHARIES S. Qnaw- Form, a citizen of the UnitedStates, resid ng at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements in Vehicle-Wheels, of which the following is a speclfication.

The object of my said invention is to provide a resilient metal wheelfor vehicles particularly designed for automoblle use wherein resiliencyor elasticity Wlll be secured through the medium of tubular spokes ofspecial design and construction, all as will be hereinafter more fullydescribed and claimed. I

Referring to the accompanying drawings, which are made a part hereof andon which similar reference characters indicate similar parts,

Figure 1 is a side elevation of a wheel embodying my said invention,

Fig. 2 a detail section 1n the dotted llne 2-2 of Fig. 1, and

Figs. 3, 4 and 5 detail views showing mod1 ficati0n83 In said drawingsthe portions marked A represent the hub, B and C the two members of therim, and D the tire, which parts are or may be of any appropriate ordesired construction and arrangement. I prefer an all metal rim composedof the two parts and C, as shown, the part B being the ord1nar rim forholding the tire D and the part a hollow metal ring formed of sheetmetal, preferably rectangular in cross section and secured to the memberC by welding or riveting, or by other appropriate means, the free edgesof the ring being welded to the face of member C.

The spokes consist of corrugated metal tubes 11 the inner ends of whichare secured to the hub in metal sockets 12 by bolts or rivets 13, andthe outer ends of which are secured inthe member C in sockets 14 bywelding, or other appropriate means. In Fig. 2 the socket for receivingthe outer end of the spoke is formed by punching inward, while in Fig. 3I show it formed by punching outward. In Fig. 4 the end of the spoke isshown as secured to the out-turned flange on the member C by abutt-weld. These forms are shown to illustrate a few of themodifications that readily suggest themselves.

The invention resides chiefly in forming rigidity of the spoke from thecenter of the wheel toward the rim and thus secures a uniform rate ofdeflection, which is important in wheels designed for the purpose forwhich this is intended. The corrugations run circumferentially aroundthe spokes, as shown,

and the term corrugated circumferentially as used herein is intended tomean that the spokes are so formed.

It will be understood, of course, that any metal found appropriate forthe purpose may be used, but steel tubing will probably be preferred.

This application is filed as a continuation of application No. 285,178filed March 26, 1919.

Having thus fully described my said invention, what I claim asnew anddesire to secure by Letters Patent, is:

1. A wheel composed of a hub, a rim and spokes interposed between saidhub and rim consistin of metal tubes corrugated circumferentialii 2. Awheelcomprising a hub, a rim and spokes connecting said hub and rimconsisting of metal tubes corrugated circumferentially, the corrugationsvarying in length from hub toward the rim, substantially as set forth.

3. A wheel comprising a hub, a rim, and spokes, said spokes consistingof metal tubes formed with circumferential corrugations varying inlength from the hub toward the rim and secured to the rim by connectionwith a hollow ring member thereof, substantially as set forth.

4. A wheel comprising a hub, a rim consisting of two members securedtogether the inner member being hollow, and tubular my hand and seal atIndianapolis,- Indiana, spokes circumferentlally corrngated and this28th dayof August, A.
